The suburb (Harrington Park, NSW) doesn't have any tertiary roads - I went for a drive there this afternoon. It's all just residential - a suburb full of McMansions. Whoever tagged them was being a bit careless. I've fixed all the tertiary roads, corrected a lot of errors from some sloppy Yahoo tracing, and added a lot of missing street names. You do realise that just because a road has houses on it it doesn't mean it has to be residential, right? If a road is secondary or tertiary, then that over-rides the residential tag. Just looking at the area quickly, from satellite overview, I would say that Fairwater drive should be tertiary. The vast majority of traffic on the street would be coming from or going to other roads, not the street itself, and it is a feeder road for different parts of the suburb. So are Harrington Parkway, Royal George Drive, and Sir Warwick Fairfax Drive. I'd want to see the ground, but I wouldn't be surprised to see the last one as secondary. It's a very rare suburb that has no tertiary roads. Stephen Yes, I know it looks that way from the satellite overview. But when you drive through, it's really just a convoluted residential road. From around the 1970's most Sydney suburbs were planned so that the road map looks like a bowl of spaghetti, specifically to discourage drivers from using the interconnecting roads as local short-cuts. All the roads you mentioned are almost completely residential (there is the odd school), and their only function is for residents to get out of the suburb. By contrast, in my suburb of Ruse, NSW (not far from Harrington Park - look it up) there is a major road (Junction Road) through the middle of it, rendered as tertiary, and always  coloured yellow in street directories. It's not just the way out of the suburb, it's the way through the suburb for people travelling through Ruse from adjacent suburbs. I feel that this is what qualifies a road as tertiary. Richard
